Video: Red Bull's Latest Aerial Ballet
Red Bull Wednesday shared video of one of its latest sponsored adventures -- five wingsuit skydivers joining up with and maintaining formation with two sailplanes in a dive over Austria. The team flew two aerobatic LET L-13 Blanik sailplanes and just to complicate things, the lead flew inverted and one skydiver formed up in between the inverted and upright glider. The skydivers and gliders came together in formation at roughly 12,000 feet. The sailplanes wore wingtip-mounted smoke canisters and one skydiver wore one on an ankle. The trick of the task was mating airspeed and descent rates and this time all members performed flawlessly.
Generally, wingsuits manage their best glide (roughly 2.5:1) at close to 75 mph. The Blaniks are a 1950's-era metal design and manage close to 30:1 at about 55. For the stunt, the team found a common airspeed closer to 110 mph, then found and held formation with the requisite precision.
